Value Collection 530-4210 5C Square Steel Collet 5/32 in

Product Description

The VALUE COLLECTION 530-4210 is a 5C square steel collet designed for use in collet-style workholding systems on lathes, collet closers, and indexing fixtures. Sized at 5/32 inch for square stock, it features a Total Indicator Runout (TIR) of 0.0005 inch, an internal thread of 1.041 inch-24, and an external thread of 1.242 inch-20. The collet is machined from steel for durability and dimensional stability under repeated clamping cycles. Machinists and toolroom technicians install this collet when precise, repeatable workholding of square bar stock is required at the spindle.

This collet is suited for production and toolroom environments where 5C-compatible spindles are in use. The square profile grips square bar stock securely, making it appropriate for turning, facing, and light milling operations on lathes or collet-closer fixtures equipped with the 5C standard. It is a direct-fit replacement or additional collet for any machine tool spindle accepting the 5C external thread and internal thread dimensions specified above.

Key Features

• 5/32 inch square bore for accurate grip on square bar stock
• TIR of 0.0005 inch for precise, repeatable workholding
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C spindle specs
• Steel construction provides strength and resistance to deformation under clamping load
• Compatible with the widely used 5C collet standard found on many lathe and fixture setups

Compatibility

Designed as an OEM-style replacement or supplemental collet for machine tool spindles and collet closers built to accept the 5C collet standard with a 1.242 inch-20 external thread.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the collet. Clean the spindle bore and collet taper of chips and debris before seating to maintain TIR performance. Do not overtighten the collet closer draw tube, as this can distort the collet and increase runout.
